Sun's foundation-level sunlight qualified Java Programmer (SCJP) for normal variation 6 is a must have for any Java programmer, and is a prerequisite for Sun’s forte certifications. This source is vital coaching for the SCJP and focuses seriously at the ability set that solar expects its SCJPs to have, with various examples, routines, and real-world situations to offer readers the instruments had to use what they research.

Write down the remainder. Now do the same with the quotient, writing the new remainder to the left of that from the previous operation. Keep looping until the quotient is less than the target base. The following table shows the conversion of the decimal number 747 to a hexadecimal notation: Table 3-2. A base conversion example Operation and Integer Quotient 747 / 16 = 46 46 / 16 = 2 no operation Remainder (decimal) Remainder (hex) 11 14 2 B E 2 Take a look at the table’s far-right column. Reading it bottom up, we get 2EB16, which is exactly 74710.

When you want to refer to the variable, you only use its name. Assign a value to a variable (after it has been declared) in the following fashion: variableName = anyValue You use var only once per variable. A global variable can be created simply by assigning it a value without the var keyword. Local variables inside functions, on the other hand, must be declared with the var keyword. As in many other programming languages, JavaScript allows you to declare numerous variables in the same statement by using a comma to separate them: var variableName1 = initialValue1, variableName2 = initialValue2, ...

Additionally, a floating-point number may include an exponent specification of the form e±exp. Since there is no explicit declaration of data types in JavaScript, the floating-point format is implicitly determined by the literals that are assigned to the variables. 1 * 1012 2 * 10-12 Notice that the exponent specification can be in uppercase or lowercase characters. Floating-point math is much more difficult than integer math and is the source of many bugs. Overflow describes the situation in which the exponent Chapter 3 (2 * 80) + (7 * 81) + (4 * 82)+ (1 * 83) = 2 + 56 + 256 + 512 = 82610 30 n Chapter 3 of a floating-point number exceeds the upper limit.
